Abstract

Music is an example of evolutionary convergence: Similar sound expressions can be found in birds, dolphins, wolves and in humans. This is evolutionary convergence. Present-time psychological research about the gender differences seems to support the statement of philosopher Friedrich Nietzsche: In the true man there is a child hidden – up ye, women, discover the child in man! Monogamy is common among primates and among birds. This is evolutionary convergence, too, and might be related to the ability to communicate with sounds in a sophisticated way. My paper also deals with laughter, weeping and blushing, highlighted as Irenaeus Eibl-Eibesfeldt might have interpreted their evolutionary origin.
